A catamaran is a vessel with twin hulls. Commercial catamarans began in 17th century England. Separate attempts at steam-powered catamarans were carried out by the middle of the 20th century. However, success required better materials and more developed hydrodynamic technologies. During the second half of the 20th century catamaran designs ...
Jim Brown is a multihull sailboat designer who collaborates with John Marples. [1] The pair are responsible for the Constant camber, Seaclipper and Searunner [1] series of trimarans. Early in his career, Jim Brown was inspired by Arthur Piver. Jim is now retired. [1]
Derek Kelsall (15 May 1933 – 11 December 2022) was an English multihull sailboat designer latterly resident in New Zealand. [1] [2] He began his career in surveying and in the oil industry, but found the lure of boats too great to ignore. Born in north Wales on 15 May 1933, he died in Thames, New Zealand on 11 December 2022, at the age of 89. [3]
Wharram was born in Manchester, England.In 1953, after long studies into the records of boats of the Pacific in the libraries and museums of Britain, and inspired by Eric de Bisschop's book The voyage of the Kaimiloa, [1] he designed and built the first British ocean-going double-canoe-catamaran, the Tangaroa (length 23 feet 6 inches (7.16 m)) and in 1955–56 sailed with Jutta Schultze ...

This initial success inspired others to build similar boats. Crowther then studied electrical engineering in Melbourne [2] and in the early 1960s became involved in multihull design and the Amateur Yacht Research Society. [3] In 1962 Trio was built based upon his designs. [2] [4] Crowther's next design was the Kraken 25, garnering some ...
He constructed his first trimaran, a 40-footer with $600 that he borrowed from his grandmother in 1961. Although influenced by Piver's designs, Horstman diverged by using Boeing technology to make flush-decked sailboat ""with accommodation in all three hulls—the dreadnaught class of trimarans" [ 2 ]
A small waterplane area twin hull, better known by the acronym SWATH, is a catamaran design that minimizes hull cross section area at the sea's surface. Minimizing the ship's volume near the surface area of the sea , where wave energy is located, minimizes a vessel's response to sea state, even in high seas and at high speeds.
